Selecting Compatible Lead Screws and Nuts
More
Precision Acme Lead Screws and Nuts
Pair with a motor in automated motion and positioning applications. A tight thread fit allows these lead screws and nuts to make accurate, repeatable starts and stops. Also known as single-start and self-locking lead screws and nuts, they have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won’t unexpectedly move when the lead screw is at rest. To ensure compatibility, please select components that have the same thread direction and size.
Cast iron nuts have good machinability and high strength. 932 bearing bronze and 673 bronze nuts are wear resistant. They have good machinability and fair corrosion resistance.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Combine externally threaded nuts with a flange to create a custom flange nut.

Acme Lead Screws and Nuts
Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. To ensure compatibility, please select components that have the same thread direction and size.
932 bearing bronze components are more wear resistant than brass components. They have good machinability and fair corrosion resistance.
Travel distance per turn, also known as screw lead, is the distance a nut or handle moves with one revolution of the lead screw.

Round nuts move objects along the length of a lead screw.
